Implement automatic client reconnection with exponential backoff and heartbeat timeout

Browse source 
- Add heartbeat timeout to client control connection using server heartbeats for dead connection detection
- Introduce exponential backoff with jitter for reconnection delays
- Add CLI flags: --no-reconnect to disable auto-reconnect, --max-reconnect-delay to configure backoff cap
- Classify authentication errors as fatal (never retried), all others retried automatically
- Configure TCP keepalive on control connections for OS-level dead connection detection
- Update documentation (README.md, CLAUDE.md) to describe reconnection behavior and new flags
- Add unit tests for backoff logic and error classification
